Application filed June 21, 1915. Serial No. 35,317.

To all whom it may concern:

Be it known that I, Jean 1. SELTEN- REIGH, a citizen of the. United States of America, and a resident of Chicago, in the county of Cook, in the State of Illinois, have invented new anduseful Improvements in Collar-Molding'Machines, of which the following, taken in connection with the accompanying drawings, is a flllLClGilI, and exact description. p

This invention relates to certain improvements in collar molding and edging machines of the class set forth in my co-pending application Serial No. 687,153, filed March 29, 1912, in which thefoldedcollars are placed by hand upon one or more circular forms which are then shifted and brought into pressing coaction with heated heads and automatically given a rotary oscillating movement for shaping the collar and ironing or smoothing its folded edge to remove any'roughnesses, wrinkles, swells, or other irregularities in such fold or adjacent portions of the collar. i

With this class of machinesutilizing a rotary and vertically, movable carriage forming a support for a plurality of eccentrically positioned collar supporting'forms or rings, the power for raising the carriage vertically, and thereby the rings, to bring the rings into pressing coaction with the heated heads, being applied axially of the carriage through the inediumof a vertically disposed shaft, the pressing coaction of the collar supporting ring and the shaping head tends to tilt the carriage and distort the parts whereby the collar supporting rings become out of alinement with the sockets in the shaping heads, whereby a wedging action takes place between the collar supporting ring and the socket tending to further'distort the carriage and the ring-supporting elements, resulting in an uneven pressure upon the edge of the collar to be molded.

My improvement, therefore, consists in applying the pressure for molding and shaping the collar at two spaced points :-first, axially of the carriage, and, second, axially of the collar supporting ring, rather than solely axially of the carriage, the means for applying the pressure axially of the ring insuring an exact alinement of the ring with "the socket in the head and relieving the carriage of a portion of the strain of forcing the elements into pressing coaction to mold the collar.

The broad idea of the invention contemplates the use,in combination with a rotatable and vertically movable carriage carrying eccentrically positioned collar supports, of means for simultaneously applying pressure axially of the carriage and axially of the collar supporting ring.

Other features of the invention relate to the combination with the means last described of two ,coacting pressing elements,

one of the same adapted to have a rotary or rotary oscillating movement during the pressing coaction.

Other objects and features relate to the specific construction and arrangement of the parts by which the above objects are accomplished, as will more clearly appear from the following description, taken in connection with the accompanying drawings, in which- Figure 1 is a top plan of a collar molding and edging machine embodying the various features of my invention.

Fig. 2 is an enlarged vertical sectional view through one of the ironing heads and collar supporting forms, together with the adjacent portion of the supporting parts for said form, taken on line 22, Fig. 1, the partsbeing shown in their coacting pressing position with an interposed collar between the head and form, and also showing the spring fingers for retaining the collar upon the form while the latter is being forced to a rear elevation of the machine.

Fig. 6 is a central vertical sectional view of the same machine, taken on line 6-6, Fig. 1.

' The machine comprises an upright supporting frame --1'- upon which is'mounted a work-table 2 and upright brackets 3- rising from the table for supporting a plurality of, in this instance two, shaping 'or' ironing heads -4, leaving suflicient space between the table 2- and the heads, and also between the brackets 3 for the free reciprocatory and rotary movement of as they are brought into tral hub havinga' tapering opening therethrough fitted tightly upon a. correspondingly tapered upper, end of the shaft and heldiin place vby a cap screw -'25 which enters a threaded hole in the adjacent end of'the shaft, said support being also provided witha'series of, in this instance four,

radial arms of equal length spaced uniform distances apart"circumferentially and provided at their outer ends with sockets 26- for receiving the hubs as -27 of the ring supports l8-, the rings being locked by pins -22-Q 1 a The hubs 27are preferably hollow so as to bear, against the bottom of the socket i or bearing 26 and upper side of the hub -27 for yieldingly supporting the forms thereby causing the collars to be pressed into and against the bases of the grooves 1O. under ayielding pressure and assuringa perfect contact of all portions of the fold-of the collar with the base of the groove even though the thickness of the collar at the fold may vary slightly at difierent points.

. In order to give the collar supporting forms -5 a rotary oscillating movement and returned from pressing coaction with the head, the hub .27 is provided with a pair of obliquely disposed slots -27 positioned diagonally of the hub, and the bearing or socket 26 is provided with a pair of threaded apertures for. the reception of externally threaded pins 26 havingtheir ends projecting into the slots 27- for giving to the collar supporting forms 5 andhub 27-- a rotary oscillating movement as the same is depressed with respect to the bearing 26- by the pressing coaction with the shaping headand returned to normal position as released from pressing coaction by the spring 29, whereby the collar is molded, ironed and edged in a single operation. I

The shaft 7 is supported in an upright position midwaybetween and some distance in front of the heads l and is adapted to be rotated and moved axially to successively register each pair of collar supporting forms with the grooves in the heads and to movefsaid forms with the collars thereon into and out of'said grooves and for this purpose I have provided the top of the main supporting frame 1- with a hollow hub .30- in which is journaled a rotary sleeve ,-31- having a centrallborein which the I as shaft -7- is splined for axial movement and for rotary movement with the sleeve.

This sleeve 31- is inserted from the underside upwardly through the opening in the top of the frame 1- and extends some distance above said top, its upper end being threaded externally for receiving a nut -32 for engaging the upper side of the frame and holding the sleeve in operative position against downward movement said nut being held in its adjusted'position by one or more set screws 33. v p p The lower end of the sleeve 31- is provided with an enlarged integral disk 34 and mutilated bevel gear 35, the disk .34 being engaged with the underside of the hub -30 and together with the nut -32 holds the sleeve against endwise movement in either direction and at the same time permits free rotation of the sleeve and haft.

' The disk -34- constitutes one of the locking elements for holding the sleeve and shaft against rotation when the collar supporting forms are in pressing coaction with the heads -4., and inasmuch .as each pair of forms are registered successively and alternately with the heads, it is necessary to lock the shaft against rotation at each half turn and for this purpose the periphery of the disk 34 is provided with diametrically opposite notches or recesses 36 for alternately and successively receiving a movable locking pawl or detent -v37'-.

The pawl -37- is pivotally. mounted at 38 in a bracket 39 secured to and depending from th'esunderside of the top of the main supporting frame -1 atthe rear side of the disk 34, said bracket being provided with a vertical groove in which the pawl 37 is adapted to play and serves to hold said pawl against undue lateral movement.

This pawl is spring pressed into holding engagement with the disk 34' by means of a coil spring.l0 which is mounted in a suitable socket in the bracket 39 and engages the rear edge of the pawl so as to force the latter forwardly toward the disk and at the same time permitting said pawl to be forced from its holding position at the proper time in a manner hereinafter described.

The bevel gear or pinion -35 is adapted to be driven by a mutilated gear -41- which is mounted upon a horizontal shaft --42, said gear and pinion being proportioned and mutilated in such manner as to rotate the shaft intermittingly one-half revolution at a time and to hold the shaft 7- against rotation while the shaft 42 continues to revolve. For this purpose the ratio of the gears 35 and l1 is one to four, the gear 35 being provided with diametrically opposite toothed segments and will when necessary.

intervening :diametrically opposite smooth portions, while the gear .41is provided :with ra toothed segment having about the same number of'teeth as one'of the segments "of the :gear or sufficient so that when the toothedsegment-0f thergear 4:1 is in mesh with either of thertoothe'd segments 'on the gear -3:5\, it "will rotate the shaft zonefhalf revolution, the remaining portions of the gear 4:1 being smooth fortsli'ding contact with the smooth portionseof the gear 35, thereby holding the shaft against rotation irrespective of the locking pawl "The shaft '42 is journaled' in suitable iibearings -43 on the main supporting frame -'1 and is provided with a worm :gear which meshes with a worm -;45 on a main d1 'iving shaft +46.

'.This:shaft-46 is also j ournaledfin-suitable bearings 47 on the main supporting frame and is provided with-a clutch section ,4:8 splined thereon and movable into and out of engagement with a correspond ,ingclutch section .49 on the adjacent end of ;a driving gpulley '50 which is loose on the. shaft and adapted to be connected to any available sourceof power not shown, said shaft 4:6 being also provided witha iihand'wheelr5lon its outer'end whereby it maybe rotated to operate the machine at Thesliding clutch section .48 ismoved into and out of interlocking engagement TzWlth the pulley 50 by means of a bellicrank lever -52 which is secured to a crock shaft 5'3'a11d is provided with. op- ;posite pedals--54 and 55- for rocking -the=shaft in reverse directions.

This rock shaft -5? is journaled in the main supporting frame andcprovided with an upwardly projecting arm 56 rigid thereon and having its upper end engaged in an annular groove in. the clutch "section -:4:8"so that by rocking thelever 52'in one direction, as for example, 'by depressing the pedal -55 the clutch member 48- will be thrown into lockingengagement with the clutch section 49 to lock the pulley 50 to the shaft 46 or when rocked in the other direction by means of the pedal -754.,' the clutch section f8 will be thrown from its locking position, thereby releasing: the pulley and permitting it to rotate continuously independently of the machine. I 7 1 .;The means for reciprocating the vertical shaft 7- and collar supporting forms 5 carried thereby consists of a semi-circular cam 57 rigidly secured to the.- shaft -42 and adapted to engage a roller bearing -58 on the underside of the top of a vertically movable yoke 59 which surrounds the cam'57 and shaft and :provided with upwardly projecting .guide pins -160-"- playing tin suitable gui'dei openings infthe top tof the imi tin supporting frame i.lc. so as ito cause the yoke to vmove vertically in a. straight line,- .iit being understood thatt-he opening in the yoke +59'- in which the cam "57-t:'-plays is rof sufli'cient size to permit free'zpla'y of :thesccam without liability rof. engaging any other: portions of the yoke except.the.roller :-'58--..

The .rock arm --62+ is proride'd with :a :suitablespring :63 connected to thero'ck arm and to the :frame -1 'for-inormally holding the armat its :limit =of downward movement on the shaft 63'' and=the.-..spring is of suffi- 'cient strength to inorma'llzy ill'OhCl ithe Jupper portion of the slot *.62-c.in engagement withr'the shaft -..63 until 'the :shafthas been raised a suflicient rdistance to bring the collar supporting forms 5 into pressin-g coaction with the sockets in the :shaping heads -4 atiwhich timelthe yoke 59- continues to :raise the .arm -e62'i by moving the slot .62" upwardly "along the shaft ''.63 against the action of the spring ''63, for 1 a purpose hereinafter described. Thepinsrorrods+60:are so formed and arranged thatthey extend upwardlyithrough the table--2- :attpoints disposed axially of the shaping heads .and,3there'fore, axially of the-collar supporting I forms, as they are brought' :under tion of theeshaft -7 :and. carriage .6-fi, and these shafts .are of such length that when the carriage e(5is at thetlimitof its downward movement the rods "60 do not interfere with therotation of thewcarri'age and the forms supported thereby.

The operation of this portion of the machine is as follows: As the camzstarts to raise the lever 62, "the first movement is the raising of the shaft .7 andcarriage.- 6- until the collar supporting forms 5- come into pressingcoaction with the sockets or grooves in the heads 4, at which time the force required to 'raise'the shaft 7 b'ecomes'sufii'cient to overcome the tension :of spring 63'and the slot 6'2- moves upwardly along the :shaft 63- so that the .rods -60- continue to move upwardly :after the shaft has the heads by 'rotaby means of the shaft practically ceased its vertical movement until the rods contact with the heads of the bolts 28- at which time the pressure is applied to the collar supporting forms both 7- and carriage 6, and by means of the rods 60 act ing directly upon bolts -28-, the pressure at all times being a resilient one due to the inclosed spring 29. The simultaneous application of pressure axially of the carriage 6 by means of shaft 7 and axially of the form 5-- by means 'of rod -60-, prevents any tendency to distort or bend the frame during the time when the greatest supporting form and its carriage, and the head of the bolt -28 is preferably countersunk to form a seat for engagement with aspherical or conical end of the rod 60- whereby an exact alinement of the forms with the heads is assured (see Fig. 2).

Upon the return movement of the forms,

the spring -(i3- first moves the slot -62- downwardly until the upper end of" the slot contacts with the shaft 63'' at which point the shaft -7- begins to move downwardly to return the forms to starting position.

At the front of the frame is another cross rod-66 disposed in substantially the same horizontal plane as the cross rod 68 and to these cross rods are rigidly secured upwardly projecting brackets 67 carrying aforwardly and rearwardly extending rock shaft ''68- to which is secured one end of a laterally projecting rock arm 69- having its other end engaged with the upper face of a collar 70 rigid on the vertical shaft -7 for positively forcing the shaft downward in case it should fail to drop by its own gravity.

For this purpose the rear end of the rock shaft -68- is provided with an additional rock arm -71 rigidly secured thereto and adapted to be engaged by a coacting arm -73- on the rear end of the horizontal shaft 42- asshown more clearly in Figs 1, 4 and 5.

It is now apparent that the arm -73- is mounted on the same shaft as the mutilated gear -4land cam 57-. This cam 57 'is adjusted relatively to the toothed segment on the gear 4c1-- so that the central portion of its highest concentric surface contacting with the roller 58,- of the yoke -59- is diametrically opposite said toothed segment and,'therefore, elevates the shaft and collar supporting forms carried thereby into pressing coaction with the shaping heads -4 while said shaft is held against rotation or through practically half a revolution of the gear -l=1--, such vertical movement of the shaft and collar forming heads being accompressure is exerted upon the collar plished through the medium of the yoke As soon as the high portions of the cam have passed the roller'58 on the yoke 59- during its continuous revolution, the weight of the shaft and collar supporting forms mounted thereon is-ordinarily sufficient to return said forms'to a plane below that of the shaping heads l but in case these. parts should not return to their starting positions by gravity, the arm -73 on the shaft -42 will have rotated into contact with the rock arm -'71, thereby operating the rock shaft -68 and rock arm 69- to positively depress the vertical shaft and collar supporting forms below the plane of the shaping heads -4- before the toothed segment of the gear 41- engages the teeth of the pinion 35-'to rotate the vertical shaft and forms carried thereby for the purpose of bringing another set of such forms with the collars thereon into registration with the shaping heads preparatory to raising said forms to repeat the pressing operation previously described. I

During this operation'of raising'and lowering the collar supporting forms into and out of pressing coaction with the heads l-, the shaft is positively held against rotation by the locking pawl 37-- and it therefore becomes necessary to force this awl from its locking position before the toothed segment ofthe gear -41- engages the teeth of the pinion 35' to rotate the shaft -7 and for this purpose I have provided the rear face of the gear 4:1 with a cam 80- extending concentrically across the back and beyond the ends of the toothed segment of the gear -41-, the ends of said cam being beveled so as to ride easily against the front face of the pawl 37 to force the latter rearwardly against the action of its retracting spring out of locking engagement with the disk 34, thereby permitting the rotation of the shaft 7- and forms -5 by the intermeshing teeth of the gears -41 and -35-. i 1

After the collars are pressed, they are removed by hand from the forms -5- an placed into a circularlchute -81 which they may gravitate intoan underlying receptacle not shown. I Operation: Assuming that the collar supporting forms are in their elevated positions as shown in Figs. 3, 4 and '5, in which one pair of forms are in pressing coaction with the heads a while the other pair are exposed to the front of the machine, the collar which have been previously folded are then placed by hand upon the upper edges of the forms -5, while those which have been previously placed in the same manner forms carried thereby, andthrough upon the; forms;wh,ieh are in. pnessinggcoi heads and at the;
